This invention relates to couplings for hoses of all kinds, my principalobject being' ing together of any'parts being necessary,

While at the same time the couplin when made will have the necessaryrigidityand water tightqualities.

A further object of the invention is to produce a simple and inexpensivedevice and yet one which will be exceedingly effective for the purposefor which it is designed.

These objects I accomplishiby means'of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claim.

In the drawings similar characters of reference indicate correspondingparts in the several views:

Fig. 1 is a side elevation of the male'element of the coupling.

Fig. 2 is a side elevation of the female element of the coupling.

Fig. 3 is a side elevation 'of thecoupling parts assembled.

Fig. 4. is a top plan view of the same.

7 Fig. 5 is a sectional elevation of the assembled structure.

Referring now more particularl-y tothe characters of reference on thedrawings, the

coupling consists of two main tubular members 1 and 2. The member 1 istapped at one end as at 8 to receive the male element 1 of an ordinarycoupling which is secured to a length of hose 5jas usual. Toward 1ts opposite end the member 1 is provided wlth a straight-sided portion 6 ofsomewhatreduced diameter having short opposed palrs of trun nions 7projecting outwardly therefrom. The member 2 at one end is formed as asleeve 8 to fit over the portion 6, the sleeve being provided withlongitudinal and opposed pairs of slots 9 open to thead acent end andadapted to receive the trunnions therein. At its opposite end the member2 is threaded 0 as at 10 to engage the female member a'standardcoupling, which is attached to another length of the hose 5. The innerend of themember 6 when projected into the sleeve Sis adapted to abutagainst a compressible washer 12 of rubber orethe like which is pressedinto a groove 13 formed in the member'2-inwardly of the slots as showninFig.5.-- f' i 1 irojecting. fronrthe member 2 of opposite sides-thereofand-longitudinally alined with one pair of the slots 9 are short pivotpins l ion' which are turnable bellcranklevers I 15. Thelong arms ofthese levers are connected by an integral cross piece 16 which extendsacrossthe member 2, said cross piece being provided with suitable fingergrip means 17 so that the leverssmay be easily manipulatedas aunitu.Theshort arms of the levers project away from the slots and areconnected teens end .oflongitudinally' extending arms-18 which on theiropposite ends are formed with hooks 19 for=detachableengagementiwith.the trunnions 7. Across membersQO connects the arms and extendsoveri'the sleeve of the member 2to prevent the arms from droppingdownbelowflthe plane of the slots 9.. This cross member of coursecprlojec-tsfrom the edges of the arms oppositev to the open ends of the hooks. IThe partsof the structure are so arranged ithat when the hooks areengaged. with'thetrunnions and the member 6 is pressingly engaged' withthe washer 12, the pivotal connection of the arms 18 with" the lever.arms is then belowv the dead center line of the trunnions are held infirm andwatertight engagement with the washercdisposed therebetween. Theouter ends of thefle've'rs 15 then lie close to the coupling member ll.When it is desired todisconnect the coupling it is only necessary toswing the levers up by meaiis of the grip 17 when the short arms of thelevers will swing ahead of the dead center line as shown in Fig. 1,causing the hooks to be retracted from the trunnions. Said hooks maythen be raised from the path of the out- 5 ward movement of thetrunnions in the slots and the parts disassociated from each other bysliding movement. WVhen connecting the parts of the coupling togetherthe above operations are of course reversed.

The position of levers and the cross member 16 thereof when the parts ofthe coupling are engaged tends to prevent the levers from being possiblyraised to release the hooks when the structure is engaged with 15 theground and the hose is being drawn along. Connecting the two levers andthe two arms to each other, of course causes the movements of theseparts to take place simultaneously so that a suitable manipulation ofthe mem 2 her 17 will cause hooks to be actuated at the same time.

The use of two pairs of trunnions and slots enables the parts to befitted together with never more than an initial quarter-turn to positionthe slots relative to the trunnions being necessary. This makes thedevice very adaptable for fire hose, which cannot very readily berotated to any great extent.

From the foregoing description it will be as readily seen that I haveproduced such a device as substantially fulfills the objects of theinvention as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended claim.

Having thus described my invention what I 3 claim as new and useful anddesire to secure by Letters Patent is:

A hose coupling comprising separate members arranged to be slidablyfitted together at adjacent ends, opposed trunnions on one .5; member,hook-arms for engagement with the trunnions, bellcrank levers pivoted onthe other member and to which the arms are pivoted in offset relation tothe pivots of the levers, an operating connection between the in outerends of the levers extending across the coupling, and stop meansprojecting outwardly from said other member to be engaged by said leverson opposite sides of the coupling member and limit the movement of thelevers when the pivot of the hook-arms is just beyond dead centerposition with respect to the trunnions and lever ivots and permittingsaid connection to e then spaced from the coupling.

' In testimony whereof I afiix my signature.
